Objective To investigate the efficacy and safety of percutaneous nephrolithotomy with balloon dilatation and open surgery for benign ureteral stricture. Methods Computers were searched for PubMed, Cochrane Library, Embase, CNKI, Wanfang, and Wei to popularize the Chinese biomedical literature library. A randomized controlled trial(RCT)was performed to collect and screen percutaneous nephrolithotomy for balloon dilatation and conventional open surgery for benign ureteral stricture. The duration of surgery, intraoperative blood loss, postoperative hospital stay, and total were evaluated for the two surgical procedures. Differences in efficiency and other aspects. The search time is for the construction of the library until May 28, 2018. Meta-analysis was performed using RevMan 5.3 software after screening, data extraction and quality evaluation of the literature. Results Seven studies were included in the inclusion criteria. A total of 427 patients, including 207 in the balloon-expanded group and 220 in the open surgery group. The meta-analysis showed that there was no significant difference in the total effective rate between the two groups(P>0.05). There were significant differences in the operation time, intraoperative blood loss and postoperative hospital stay between the two groups(P<0.05). Conclusion Compared with traditional open surgery, sacral percutaneous nephrolithotomy with balloon dilatation can achieve higher surgical safety under the same therapeutic effect.
